"The purpose of the study is to bring out often-neglected facts concerning dissimilarities in the lifestyles and consumption patterns of women and men, and thus in their environmental impact, by describing how men, primarily through their greater mobility and more extensive travel, account for more carbon dioxide (COB2B) emissions than women, in both rich and poor countries. The study points to how a changed behavior among men – notably rich men who are decision-makers - can be crucial in addressing climate change and in enhancing the opportunities of all human beings to enjoy sustainable development."
